Pro Tip 1/3Context
A rheostat is mainly used in electrical engineering and applications.
In theater, rheostats are used to dim lights for dramatic effect.
Pro Tip 2/3Usage
When using a rheostat, ensure that it is rated for the current passing through it.
It should not be overloaded, as this can cause damage.
Pro Tip 3/3Common Mistakes
It's important not to confuse a rheostat with a potentiometer, which has different applications.
While both are variable resistors, rheostats can handle higher currents.
